MARTIN KETOHUM, OF AVON, NEI/V YORK, ASSIGNOR OF ONE-HALF HIS RIGHT TO WILL D. GRANDALL, OF SAME PLACE.

IMPROVEMENT IN BOLT-HO LDERS.

i Specification forming part of Letters Patent N 0. 212,013, dated February 4, 1879; application filed. December 7, 1878.

Figure 1 of the drawingsis a representation of a wheel, showing my bolt-holder applied; and Fig. 2 is a perspective view of the rackbar.

My invention relates to a device for preven ting bolts from turning in their sockets while the nut is being turned on or off; and the novelty consists in the construction and arr'angement of parts, as will be more fully hereinafter set forth, and pointed out in the claim.

In carrying out my invention I employ a body or frame having two or more arms or standards, against which the tire or other article abuts. Two standards, also rigid with this body, furnish journal-bearing for a shaft, on which is pivoted a lever which has a cogged segment, which segment meshes with a sliding rack-bar of steel, having a sharp end, which end is forcibly held against the bolthead by the lever, as shown.

My invention is peculiarly adapted to tirebolts, but may be applied otherwise with efficient results.

Referring to the drawings,-A represents the body, having two jaws or standards, A A and a guideway, A adapted to loosely receive a rack-bar, B, which slides therein, as shown. Rigid with this body are two standards, 0 c, which furnish bearings at c c for a shaft, 0, on which is hung a lever, 0, having a toothed segment, 0 which meshes with the sliding rack-bar B, and operates the same.

The rack-bar is made of steel, and has a sharp chisel-point or other end, I), which will engage the bolt-head and hold it from turning.

I do not confine myself to this exact construction, as various changes may be made without departing from the principle of my in vent-ion.

To prevent the rack-bar from becoming disengaged it may be provided upon its lower surface with a longitudinal slot, in which will operate a removable pin or lug.

What I claim as. new, and desire to secure by Letters Patent, is

The body A, having holding-standards A, guide A and standards 0 c, in combination with rack-bars B b and lever 0, having toothed segment 0 as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence .of two witnesses.
